Putting this here, so people know, if it ever becomes relevant (unlikely, but still): If you want to use my characters for anything non-profit, you may, without contacting me even (though it would be nice regardless). All I want is a small mention that gives me credit for first concieving of them. If you want to use my characters for something for-profit, if it's just a cameo or similar, you also may, under the same terms; if it's a more substantial role, I don't want to chain myself to any statement - then contact me.
